Hi Lizzie
Welcome to the forum, sorry about your diagnosis. But it could be a whole lot worse and this is a good forum where you can learn lots about diabetes and how to control it whist still living life to the full.
Have you mentioned your swollen ankles to your doctor? Has this just started happening since your diagnosis? There are lots of reasons for swollen ankles. from varicose veins to being overweight and side effects of medications and some illnesses too, so get this check out please, and keep your legs elevated as much as possible, put a few pillows or a rolled up quilt at the foot of your mattress so that your legs are higher see if that makes any difference.
I hope all goes well for you.
Karen
